> URL: https://issues.apache.org/jira/browse/PROTON-1901
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: proton-j-0.27.2, proton-j-0.28.0
> Reporter: Robbie Gemmell
> Assignee: Robbie Gemmell
> Priority: Critical
> Fix For: proton-j-0.27.3, proton-j-0.28.1

> If a session has a delivery arriving split into multiple transfer frames, and those frames are multiplexed with transfer[s] for other deliveries on the session (i.e there are multiple links on the session), then the transfer frames are mishandled.
> The handling in the transport session is essentially expecting a single outstanding delivery at a time, whereas the spec allows (and proton-j will in certain situations send) multiplexed deliveries for different links on a session. The mishandling can result in a transfer being incorrectly treated as the start of another delivery (potentially leaving earlier bits/ones incomplete) and/or merged with the wrong preceding transfer content.
